Steering device for vehicles with two front wheels

Abstract

The invention discloses a steering apparatus for a vehicle with two front wheels. The steering device comprises a fixed base connected and arranged on a central rotating rod of the vehicle with two front wheels, a rotating base arranged on the fixed base in a pivoting manner, and a steering unit arranged on the rotating base in the pivoting manner. The steering unit comprises a cross joint which is arranged on the rotating base in the pivoting manner and provided with a first pivoting part and a second pivoting part, a first steering bracket arranged on the first pivoting part in the pivoting manner, and a second steering bracket arranged on the second pivoting part in the pivoting manner; by means of the first and second steering brackets, large-angle rotation by taking the extension direction of the first pivoting part as an axis can be achieved, and then the vehicle with two front wheels is avoided shaking when traveling on a bumpy road; thereby, the whole stability is enhanced, and the impact force can be absorbed to prolong the service life of the whole steering apparatus.

Description

technical field [0001] The present invention relates to a steering device, in particular to a steering device for a vehicle with two front wheels. Background technique [0002] see figure 1 , the existing two-front wheel vehicle 1 includes a frame 11 (for the convenience of description, the part of the frame 11 is represented by an imaginary line in the figure), a central rod 12 pivoted on the frame 11, two are located in the center The wheels 13 on both sides of the rod 12, two connecting rods 14 pivoted between the central rod 12 and the wheels 13, and most of the ball joints 15 disposed at both ends of the connecting rods 14, the ball joints 15 are used for One end of the central rod 12 and the connecting rods 14 are connected, and the other ends of the connecting rods 14 are connected with the wheels 13 . [0003] When the two front-wheeled vehicles 1 are to be turned, the rider rotates the central rod 12 to drive the connecting rods 14, and then the wheels 13 are link...

AI Technical Summary

Problems solved by technology

However, the deflection range of the ball joints 15 is relatively small, causing the steering angle of the wheels 13 to be limited and unable to perform large-angle steering, which in turn affects the handling of the two front-wheel vehicles 1; and when the road surface is bumpy When the wheels 13 vibrate in the Y-axis direction, the ball joints 15 have to bear the axial load directly due to the small rotational deflection range of the ball joints 15, thus greatly shortening the use of the ball joints 15 life
